The only thing that sticks in my memory is that some devices had bugs that prevented the "read all bytes at once" sort of strategy from working properly.
Did those devices work okay with Windows?
I don't know; I'd guess they did.
Probably the most compatible approach would be to keep one strategy as a fallback. I know that until I modified "lsusb" to know about both strategies, there were devices that wouldn't deliver strings to it.
Do you remember what the failure modes were, or can you find out?
String fetches timed out, never succeeded.
Adopting a fallback strategy shouldn't be hard, assuming the device doesn't conk out completely after the first failure.
That's why we have retries ... :)
